AWS Lambda

AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. Lambda runs your code on high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, and logging.

AWS Lambda publishes 19 API contracts indexed on the APIs.io network, including Aliases API, Concurrency API, Event Source Mappings API, and 16 more. Tagged areas include Serverless, Monitoring, Observability, Logging, and Telemetry.

The AWS Lambda catalog on APIs.io includes 1 event-driven AsyncAPI specification, 2 JSON-LD contexts, and 3 Spectral governance rulesets.

AWS Lambda’s developer surface includes pricing, changelog, CLI, authentication, engineering blog, FAQ, and 47 more developer resources.

What people ask AWS Lambda 8

The questions people put to an LLM, and the jobs they hand an agent, that AWS Lambda's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

AWS Lambda Functions API Create a function via the unversioned /functions path “Can I create a Lambda function by posting to the short /functions path?” List functions via the unversioned /functions path “Is there a short /functions path without the date prefix for listing Lambda functions?” Get a function via the unversioned /functions path “Can I look up a single function through the short undated /functions path?” Delete a function via the unversioned /functions path “Can I delete a function through the short undated /functions path instead of the dated one?”

AWS Lambda Concurrency API Check a function's reserved concurrency “How much reserved concurrency does my function currently have?” Reserve concurrency for a function “How do I cap the number of simultaneous executions of a Lambda function?” Remove a function's reserved concurrency limit “How do I take the reserved concurrency limit off a function?” Check provisioned concurrency on an alias or version “How many pre-warmed execution environments does my function's alias have?”

AWS Lambda Layers API List Lambda layers and their latest version “What Lambda layers are available in my account?” List the versions of one layer “Which versions of a shared layer have been published?” Publish a new layer version from a ZIP “How do I package shared libraries as a Lambda layer?” Get a layer version and its download link “How do I download the archive behind a specific layer version?”

AWS Lambda Event Source Mappings API List event source mappings “Which queues and streams are wired up to trigger my functions?” Connect a queue or stream to a function “How do I make an SQS queue trigger my Lambda function?” Get the details of one event source mapping “What is the current state and batch size of a specific event source mapping?” Pause, resume or retune an event source mapping “How do I pause a queue trigger and resume later from the same position?”

AWS Lambda Aliases API List a function's aliases “Which aliases exist for my Lambda function and which versions do they point to?” Create an alias pointing at a function version “How do I give clients a stable name like prod that points at a function version?” Get the details of one function alias “Which version does my prod alias currently invoke?” Repoint or reweight an existing alias “How do I move an existing alias to a newer function version?”

AWS Lambda Function URL API Get a function URL and its settings “What is the HTTPS endpoint URL of my Lambda function?” Give a function a public HTTPS endpoint “How do I expose a Lambda function over HTTPS without API Gateway?” Change auth or CORS on a function URL “How do I require IAM auth on a function URL that is currently public?” Delete a function URL “How do I take down a function's public HTTPS endpoint?”

AWS Lambda Tags API List the tags on a function “What tags are attached to my Lambda function?” Add tags to a function “How do I tag a Lambda function for cost allocation?” Remove tags from a function “How do I strip outdated tags off a Lambda function?”

AWS Lambda Versions API Publish an immutable version of a function “How do I snapshot my function's current code and configuration as a version?” List a function's published versions “Which versions of my Lambda function have been published?”

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
